Energy Efficient Offshore Accommodations: A study on energy savings in offshore accommodations

Flow past a square prism: A numerical study

The ERCOFTAC test case for flow past a square-prism at a Reynolds number of 21,400 was studied numerically using the flow solver ReFRESCO. The main objectives were to evaluate the performance of a Reynolds Averaged Navier-Stokes (RANS) based turbulence models in Unsteady RANS (URANS) simulations, identify sensitivities to numerical parameters...

Transverse Strength of a Twin Hull FPSO

The size and production capacity of Floating Production, Storage and Offloading units, or FPSOs, is ever growing. SBM Offshore specialized in converting existing oil tankers into FPSOs. One of the limitations they found was the available deck space for the topsides modules. A new concept was proposed to solve this problem: a twin hull FPSO, made...

Hydrodynamic Forces on Wind Assisted Ships using CFD

With the fluctuating fuel oil prices and increasing environmental awareness more and more attention is given to durable ways of shipping cargo around the world. Reducing fuel consumption by using wind as a source of auxiliary propulsion is one way to achieve that goals. Different projects utilising Wind Assisted Ship Propulsion (WASP) have been...

Probability-based strength reassessment of corroded FPSOs using monitored loads

FPSOs are nowadays a common practice in the production of oil at sea. These ship-type offshore units, however, cannot have regular dry-docking as they have to be on field sometimes even for their entire lifetime. This is the reason why structural monitoring systems may play an important role in the safety of these units. The MONITAS JIP was...
